APG500resistance(pirani) precise transmitter is designed for vacuum measurement whose vacuum range is between 5×10-2～1.0×105Pa
The transmitter cannot be used to measure inflammable or explosive gases that can react in a certain atmosphere
The transmitter must be used in conjunction with the control display instrument or other control display instrument of the company.

danger The transmitter can only be connected to a power supply, meter or control device that is in line with the ground ultra-low voltage requirements of the ground.
The power connection of the transmitter shall be fused.
Comply with general rules and take necessary measures for process medium.
Consider the possible reaction between the material and the process medium.
Consider the possible reaction of a process medium when a product generates heat
(e.g. an explosion).
Comply with general rules and take necessary measures for all upcoming work and
keep in mind the safety instructions in this document
Before starting work, check whether all vacuum components are complete and clean before starting work.
